Abstract
1. Компактный узел возбуждения для создания круговой поляризации в антенне, содержащий разделительный ортомодовый преобразователь и ответвитель, отличающийся тем, что ортомодовый преобразователь (21), называемый ОМТ, является асимметричным и содержит основной волновод (22) квадратного или круглого сечения с продольной осью ZZ' и две ветви, соединенные с основным волноводом соответственно двумя щелями (25, 26) параллельного соединения, при этом обе соединительные щели (25, 26) выполняют в двух ортогональных стенках волновода, при этом обе ветви ОМТ связаны соответственно с двумя волноводами (35, 36) неуравновешенного ответвителя (40), при этом ответвитель (40) имеет два разных коэффициента деления (α, β), оптимизированные таким образом, чтобы компенсировать ортогональные паразитные составляющие (δу, δх) электрического поля, возникающие из-за асимметрии ОМТ (21). ! 2. Узел возбуждения по п.1, отличающийся тем, что сечение основного волновода (22) ОМТ на выходе соединительных щелей (25, 26) меньше сечения основного волновода (22) ОМТ на входе соединительных щелей (25, 26), при этом разрыв сечения образует плоскость короткого замыкания. ! 3. Узел возбуждения по одному из пп.1 или 2, отличающийся тем, что соединительные щели (25, 26) ОМТ (21), имеющие длину L1 и ширину L2, связаны с ответвителем (40) при помощи двух шлейфовых фильтров (27, 28), размещенных на расстоянии D1 от соединительных щелей (25, 26), и тем, что расстояние D1, длину L1 и ширину L2 выбирают таким образом, чтобы получить ортогональность между паразитными составляющими (δу, δх) электрического поля, возникающими из-за асимметрии ОМТ. ! 4. Узел возбуждения по одному из пп.1 или 2, отличающийся тем, что коэфф� 1. A compact excitation unit for creating circular polarization in the antenna, containing a separating orthomode converter and a coupler, characterized in that the orthomode converter (21), called OMT, is asymmetric and contains a main waveguide (22) of square or circular cross-section with a longitudinal axis ZZ ' and two branches connected to the main waveguide, respectively by two slots (25, 26) of parallel connection, while both connecting slots (25, 26) are made in two orthogonal walls of the waveguide, while both OMT branches are connected, respectively, to two waveguides (35, 36 ) of an unbalanced coupler (40), while the coupler (40) has two different division factors (α, β), optimized in such a way as to compensate for the orthogonal parasitic components (δу, δх) of the electric field arising from the asymmetry of the OMT (21) ... ! 2. The excitation unit according to claim 1, characterized in that the cross-section of the main waveguide (22) OMT at the output of the connecting slots (25, 26) is less than the cross-section of the main waveguide (22) OMT at the input of the connecting slots (25, 26), while the break section forms the plane of the short circuit. ! 3. The excitation unit according to one of claims 1 or 2, characterized in that the connecting slots (25, 26) of the OMT (21), having a length L1 and a width L2, are connected to the coupler (40) by means of two loop filters (27, 28), located at a distance D1 from the connecting slots (25, 26), and the fact that the distance D1, the length L1 and the width L2 are chosen in such a way as to obtain orthogonality between the parasitic components (δу, δх) of the electric field arising from asymmetry of OMT. ! 4. The excitation unit according to one of claims 1 or 2, characterized in that the coefficient
